[0028] like Figure 1 As shown in Figure 6, this utility model provides a wearable breast pump device that is easy to assemble, including a milk bowl 1 and a breast pumping unit 2 for providing a negative pressure source. The milk bowl 1 includes a detachably connected front shell 11 and a rear shell 12. The rear shell 12 has an outwardly open mounting cavity 103 on the side away from the front shell 11. The breast pumping unit 2 is slidably connected to the mounting cavity 103 of the rear shell 12. In this embodiment, the breast pumping unit 2 is slidably installed in the mounting cavity 103. The breast pumping unit 2 can slide relative to the milk bowl 1 along the mounting cavity 103 under force, thus realizing the assembly and disassembly of the breast pumping unit 2 in the milk bowl 1. In this embodiment, the breast pumping unit 2 does not require additional assembly structure alignment or additional accessories for installation, which greatly reduces the difficulty of assembling and disassembling the breast pumping unit 2 and improves the convenience for users to assemble and disassemble the breast pumping unit 2 themselves. In particular, wearable breast pumps require frequent cleaning of the milk bowl 1 during daily use. Since the milk bowl 1 is connected to the breast pumping unit 2, cleaning requires first emptying the milk bowl 1. The bowl 1 and the breast pump unit 2 are detached to facilitate user cleaning of the bowl 1 and to protect the breast pump unit 2 from water leakage and damage. In this embodiment, the wearable breast pump improves the assembly structure of the breast pump unit 2, making it easier for users to disassemble and assemble the breast pump unit 2. This allows the wearable breast pump to adapt to frequent cleaning of the bowl 1, improving the user experience. In addition, the breast pump unit 2 is housed in the mounting cavity 103 inside the bowl 1, which reduces the overall size of the wearable breast pump, improves its portability, makes it convenient for users to use the wearable breast pump when out and about, and enhances the user's wearing comfort.

[0029] Specifically, such as Figure 1As shown in Figure 6, the first housing 211 extends circumferentially, and the rear housing 12 is provided with a mating wall 13 corresponding to the first housing 211. The first cavity 1031 is disposed within the mating wall 13. A milk storage cavity 101 is provided between the front housing 11 and the rear housing 12. The mating wall 13 isolates the mounting cavity 103 and the milk storage cavity 101, which helps to ensure the sealing and cleanliness of the milk storage cavity 101 and prevents breast milk from seeping into the breast pump 2 and causing damage to the breast pump. Machine 2 is easily damaged; furthermore, the front shell 11 is provided with a milk pouring port 102 communicating with the milk storage chamber 101. The milk bowl 1 shell can receive the breast milk sucked out by the breast pump through the milk storage chamber 101 and pour out the breast milk through the milk pouring port 102. The front shell 11 and the rear shell 12 are detachably rotatably connected, and the rear shell 12 drives the mating wall 13 to rotate relative to the front shell 11 in the milk storage chamber 101, so as to ensure the rotational assembly of the front shell 11 and the rear shell 12.

[0030] Optionally, the mating wall 13 is preferably an annular wall extending circumferentially. The front shell 11 is also provided with a bra mounting part 111 on the side away from the rear shell 12. The bra mounting part 111 is used to install the bra 3. The bra mounting part 111 is set as a conical wall, and the mating wall 13 is located on the outer periphery of the bra mounting part 111. During the rotational assembly of the front shell 11 and the rear shell 12, the mating wall 13 can rotate synchronously with the rear shell 12 around the bra mounting part 111, which is beneficial to ensure the smooth disassembly and normal use of the milk bowl 1.

[0031] Optional, such as Figure 6 As shown, the mounting cavity 103 extends toward the milk storage cavity 101, and the extension direction of the mounting cavity 103 is parallel to the axis of the milk bowl 1. That is, the installation direction of the breast pump 2 is parallel sliding installation in the milk bowl 1, which makes the connection between the breast pump 2 and the milk bowl 1 more intuitive. Users can easily slide the breast pump 2 into the milk bowl 1 without complicated operations or alignment steps, and can quickly complete the installation of the breast pump 2, saving time. Moreover, the breast pump 2 is tightly connected to the milk bowl 1, and the breast pump 2 is not easy to slide or fall off during use, which improves the stability of the wearable breast pump.

[0032] Optional, such as Figure 1As shown in Figure 6, the front shell 11 is provided with a three-way component, which includes a bra mounting part 111, a milk outlet part 112, and a milk suction part 113 connected in sequence. The bra mounting part 111 is fitted with a bra 3. The milk suction part 113 has a milk suction cavity 1131 communicating with the inside of the bra 3. The milk outlet part 112 has a one-way milk outlet channel 1121 communicating with the milk suction cavity 1131 and the milk storage cavity 101. The milk suction part 113 is covered with a flexible diaphragm 4. In this embodiment, the flexible diaphragm 4 is configured as a sleeve-type diaphragm, which is thinner and lighter, which helps to increase the volume of the negative pressure chamber 141, thereby improving the milk expression effect. The rear shell 12 is provided with a mounting cylinder 14 corresponding to the milk expression part 113. During assembly, the milk expression part 113 and the flexible diaphragm 4 extend into the inner side of the mounting cylinder 14, and the flexible diaphragm 4 and the mounting cylinder 14 enclose each other to form a negative pressure chamber 141. The milk expression host 2 is provided with a negative pressure channel for outputting negative pressure. The mounting cylinder 14 is provided with a first communication port 142 communicating with the negative pressure channel and the negative pressure chamber 141. The milk expression part 113 A second communication port 1132 is provided, which communicates with the inner side of the milk suction chamber 1131 and the flexible diaphragm 4. The milk suction host 2 generates negative pressure in the negative pressure chamber 141, which drives the flexible diaphragm 4 to expand and deform, thereby generating negative pressure in the milk suction chamber 1131 to realize the baby's sucking action, and the milk is unidirectionally transported to the milk storage chamber 101 through the milk outlet 112. In this embodiment, the mounting cylinder 14 is connected to the mating wall 13, and the top of the mounting cylinder 14 forms the bottom of the mating wall 13, which helps to simplify the structure of the rear shell 12, thereby increasing the volume of the milk storage chamber 101.

[0033] It should be noted that in this embodiment, the milk outlet 112 and the milk suction chamber 1131 are integrated into the front shell 11. The bra 3 includes a fitting part 31 and a connecting part 30 connected to the fitting part 31. The front shell 11 is also provided with an assembly step 1111 located at the bra mounting part 111 and the milk outlet 112. The bra 3 is installed at the assembly step 1111 through the connecting part 30. The inner side of the fitting part 31 is connected to the milk suction part 113 and the one-way milk outlet channel 1121. On the other hand, the first communication port 142 is located at the top of the mounting cylinder 14 and corresponds to the output port 25 of the negative pressure channel in the first shell 211. The milk pumping host 2 is pushed into the mounting cavity 103, and at the same time, the first opening and the output port 25 of the negative pressure channel can be automatically aligned, so that the negative pressure channel is connected to the negative pressure chamber 141.

[0034] In some alternative embodiments, such as Figure 3 and Figure 6As shown, the breast pump host 2 includes a host housing 21, which includes a first housing 211. The first housing 211 has a receiving cavity 22 for installing a negative pressure device. The mounting cavity 103 includes a first cavity 1031 adapted to the first housing 211. In this embodiment, the outer wall of the rear housing 12 is recessed towards the front housing 11 to form the first cavity 1031, so that the breast pump host 2 can be installed inside the milk bowl 1. This helps to reduce the size of the wearable breast pump, thereby improving the wearing comfort and portability of the wearable breast pump, reducing the burden on users when carrying the breast pump, and further optimizing the user experience. In addition, it should be noted that the negative pressure device in this embodiment can refer to the design of the negative pressure pump commonly used in breast pumps.

[0035] In other alternative embodiments, such as Figure 3 and Figure 6 As shown, the main housing 21 further includes a second housing 212 disposed on one side of the first housing 211. The second housing 212 is connected to the first housing 211. Optionally, the second housing 212 extends radially outward to increase the contact area between the second housing 212 and the rear housing 12, thereby improving the installation stability of the breast pump 2. Furthermore, the outer wall of the second housing 212 is provided with at least one handle position 2121. The handle position 2121 is formed by a recess in the outer wall of the second housing 212 towards the first housing 211. The cup 1 is designed to accommodate at least one finger. By providing a handle 2121 on the outer wall of the cup 1, a fulcrum for the user can be provided, making it easier for the user to disassemble and assemble the front shell 11 and the rear shell 12. Alternatively, at least two handles 2121 are provided, with two handles 2121 spaced apart and opposite to each other on the outer wall of the second shell 212. The two handles 2121 can be arranged adjacent to each other in the longitudinal or transverse direction. In this embodiment, the number, shape and layout of the handles 2121 are not specifically limited, and the two handles 2121 correspond to different fingers of the user to facilitate the user's application of force.

[0036] Furthermore, such as Figure 2 , 3As shown in Figure 6, the mounting cavity 103 further includes a second cavity 1032 that communicates with the first cavity 1031 and is adapted to the second housing 212. The second housing 212 is embedded in the second cavity 1032, and the outer wall of the second housing 212 and the outer wall of the rear housing 12 are in the same arc surface. In this embodiment, the outer wall of the rear housing 12 is recessed towards the milk storage cavity 101 to form the second cavity 1032. The second cavity 1032 communicates with the first cavity 1031, and the bottom wall of the second cavity 1032 forms the limiting wall 1033. The mounting wall 1033 abuts against the second housing 212, increasing the contact area between the breast pump main unit 2 and the rear housing 12, thereby improving the connection stability between the breast pump main unit 2 and the rear housing 12. After assembly, the main housing 21 is housed in the mounting cavity 103, and the second housing 212 is housed in the second cavity 1032. The outer wall of the second housing 212 and the outer wall of the rear housing 12 are in the same arc surface, so that the rear housing 12 can maintain a smooth and flat curved outer wall, which is beneficial to improving the user's wearing comfort and also enhances the appearance of the breast pump.

[0037] In other alternative embodiments, such as Figure 6 As shown, the first housing 211 includes a first sidewall 2111 and a second sidewall 2112 disposed vertically, and a third sidewall 2113 disposed between the first sidewall 2111 and the second sidewall 2112. The first sidewall 2111 and the second sidewall 2112 are connected to the second housing 212, and the third sidewall 2113 is opposite to the second housing 212 and is obliquely disposed between the first sidewall 2111 and the second sidewall 2112. In this embodiment, the first sidewall 2111, the third sidewall 2113, and the second sidewall are connected. The third sidewall 2113 and the second shell 212 enclose the receiving cavity 22. By tilting the third sidewall 2113 and preferably setting the second shell 212 as an arc-shaped wall, it is beneficial to increase the volume of the receiving cavity 22 and to better install the negative pressure device. At the same time, it reduces the volume occupied by the inner wall of the mounting cavity 103 in the milk storage cavity 101, thereby increasing the volume of the milk storage cavity 101 and increasing the milk storage capacity of the milk bowl 1 shell. Alternatively, the second sidewall 2112 can also serve as the top of the mounting cylinder 14, which helps to simplify the internal structure of the rear shell 12.

[0038] Furthermore, the second sidewall 2112 protrudes downward at least partially to form a recessed wall 2114. A connecting wall 2115 is provided between the recessed wall 2114 and the second sidewall 2112. The connecting wall 2115 connects the second sidewall 2112 and the recessed wall 2114, so that the bottom of the main housing 21 forms an upper and lower two-layer structure, which can further increase the volume of the receiving cavity 22. Moreover, the inner wall of the mounting cavity 103 is adapted to the main housing 21, which is conducive to increasing the contact area between the main housing 21 and the rear shell 12 of the milk bowl 1, thereby further improving the connection stability of the milk pumping main unit 2.

[0039] In other alternative embodiments, such as Figure 6 As shown, to prevent the breast pump 2 from detaching from the mounting cavity 103 on its own, a limiting structure 23 is provided between the first housing 211 and the rear housing 12. The limiting structure 23 is used to restrict the breast pump 2 from detaching from the mounting cavity 103. The limiting structure 23 includes a first engaging portion 231 provided on the first housing 211 and a second engaging portion 232 provided on the rear housing 12. One engaging portion of the first engaging portion 231 and the second engaging portion 232 is a locking block, and the other engaging portion is a corresponding anti-detachment groove. When the main housing 21 is slidably assembled in the mounting cavity 103, the first engaging portion 231 and the second engaging portion 232 are correspondingly engaged to restrict the breast pump 2 from sliding out of the mounting cavity 103, preventing the breast pump 2 from sliding out of the mounting cavity 103 due to gravity when facing the ground, which is beneficial to protecting the breast pump 2. In this embodiment, the bottom of the main housing 21 is provided with the locking block, and the inner wall of the mounting cavity 103 is provided with an anti-detachment groove corresponding to the locking block.

[0040] Furthermore, there is a gap between the first housing 211 and the rear housing 12 that communicates with the first cavity 1031, so as to ensure the assembly and disassembly of the breast pump 2 and prevent the breast pump 2 from getting stuck in the mounting cavity 103.

[0041] Further optional, such as Figure 6 As shown, the rear shell 12 is also provided with a protrusion 2116 located in the gap. The protrusion 2116 is used to abut against the first shell 211. In this embodiment, the protrusion 2116 is connected to the recessed wall 2114 and is located above the first communication port 142. The first communication port 142 extends to the inside of the protrusion 2116. The protrusion 2116 extends into the gap and abuts against the first shell 211 to improve the installation stability of the breast pump host 2. It should be noted that in this embodiment, the limiting structure 23 is provided in the first shell 211 and the second side wall 2112. The protrusion 2116 is provided in the recessed wall 2114. The protrusion 2116 is away from the limiting structure 23 and does not affect the disassembly and assembly of the host shell 21.

[0042] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
